Hi. I'm really new to Stencyl and coding in general.
And it doesn't seem strange that you need a 20 digits number? I'd suggest looking at the design of your game and see how you can make the score with less digits instead of trying to find ways to get around that problem.
You could use 2 or more attributes to form the entire number you need Attribute 1 ... Attribute nYou start from Attribute n and see if it's bigger than 99.999.999 (8 digits). If it becomes 100.000.000 increment Attribute n-1 by 1. Then again for Attribute n-1 do the same thing, if it becomes bigger than 99.999.999, increment Attribute n-2 by 1.
The game starts at 1 and goes to over 20,000,000,000 in a matter of hours. It's an exponential game. Yes I could change the formulas, but it seems shitty that Stencyl can't solve this problem for me. If I put a number in the game regardless of the length, it should be able to use that number.
